Good name for f.byLine.map!(x => x.idup)?

Nevermind. I thought you could write "map!dup" like you can with 
most other *functions*, but "dup" is a member property function. 
In particular, things like "length"/"reserve" or whatnot are 
actually free functions that take an argument, but not dup.

So UFCS tends to blur the line between both, and what can be used 
where.
